ECO-WORTHY 12V 30Ah LiFePO4 Lithium Battery, 4000+ Deep Cycle Rechargeable Battery with BMS for Ham Radio, Fish Finder, Replacement of 12V 35AH SLA

Works great!

Have had this battery since May 2025 and it's June 2026 now and it's performed and charged flawlessly. No issues and would buy again. I wish the price would come down!

I have not had battery long enough to rate it for durability, but I do have a 20 amp/hour LiFePO4 battery made by the same company and I have had it about 2 years and it still performs great so I have no doubt this battery will also. It arrived well packaged and with good voltage. It took a 100% charge and has maintained it.

It has only 28Ah instead of 30Ah. Seems like not much, but it is 7% less. I've tried with 3 different battery testers and monitors. Discharge show only 28AH, then charge show same 28AH. tried each devise 2 times, meaning ran 6 tests. All of them show 28Ah. Tried to contact the manufacturer. Left 3 messages. I's been 2 weeks already. No response. Update: Apparently the best way to contact them was via email on their website. They explained what i should do and took great care of me. Definitely recommend!!!

This is the second of these batteries I have purchased. They work great, and I have had no issues with the my first one. I like that they are lightweight and small, and are much easier to tote around for portable ham radio use than AGM batteries. However, it would have been nice if they had included terminal screws. Now I can't use the battery without a trip to the hardware store to fine some weird metric size ones. Minus one star for that.

Used once. Left in battery box for a few months indoors. Bricked now, won't charge. Update: replacement sent, excellent communication and customer service.

I bought this battery because I had the exact same problem with a different brand of battery. It charged up fine, but after I installed it in a brand new solar setup the BMS chip failed in two days. When I pulled it from the system and put it on the smart charger, the charger would not turn on. These batteries are shipped with unbalanced cells and the lower voltage cells pull the other cells down below the BMS chip's ability to recognize the battery voltage. I had a second ECO-WORTHY 20ah battery do the same thing, but I was able to recharge it. I bought a different cheaper brand and it did the same thing, except I was able to return it and got a refund. I bought 5 batteries to replace old failing AGM batteries and of the five batteries, three of them had defective BMS chips. Each battery failed in the daytime under full sunlight. All of a sudden the inverter started beeping and registered ZERO voltage. The charge controllers were brand new and functioning properly. So far I have not heard back from this seller concerning returns or refunds. I was able to return the other off brand and had excellent customer service. Right now I don't know the status of this issue, but I absolutely Do Not recommend taking a chance on ECO-WORTHY batteries.

Evidently, they’re saying they sent me a replacement battery. I didn’t need a replacement battery. This is a good product.

Excelente batería. Excelente por su tamaño y su capacidad., la verdad es un súper precio. Más adelante haré una actualización de esta reseña en cuanto ya le haga pruebas de rendimiento con mi radio de radioaficionado. Estén atentos
